Wurth brake and chain cleaner
Wurth brake and chain cleaner, £4.99
Time used: Six months
What’s good: This gets rid of all the grit and dust accumulated on your chain or brake discs with relative ease. Spray it on, leave for a minute and then scrub it off with a toothbrush to give your chain and brake discs a lovely clean finish.
Also works extremely well at cleaning the grime from said toothbrush once you have finished.
What’s not: I use it rather enthusiastically, meaning it’s not uncommon for me to go through one can in one wash when I clean the chain and front and rear brakes.
